Domain: Eukarya Eukaryotic Cell (Has a nucleus) Unicellular and Multicellular Autotrophic and Heterotrophic May or May Not Have A Cell Wall (Made of Cellulose)   Organized into three different groups: 1 – Fungus Like 2 – Animal Like 3 – Plant Like

Plant Like Protists- autotrophs Classified Based on Chlorophyll (Coloration) Chlorophyta (Green Algae) – Ex) Volvox, Spirogyra, Ulva Ancestor to Modern Plants Chlorophyll A and B Used in cosmetics and paints and food May be unicellular or multicellular Volvox Spirogyra

Plant Like Protists- autotrophs Rhodophyta (Red Algae) - Mostly multicellular Lives at Great Depths (Absorbs Blue Light) Used in ice cream and pudding Important to coral formation

Plant Like Protists- autotrophs Phaeophyta (Brown Algae) – Ex) Kelp Multicellular Largest Algae (Up to 60 meters long) Uses a swim bladder to stay upright

Plant Like Protists- autotrophs Pyrrophyta (Fire Plants) – Ex) Dinoflagellate Autotrophic or Heterotrophic Has a flagella Can be luminescent Algal bloom (Red Tide – produces toxin)

Plant Like Protists- autotrophs Bacillariophyta (Diatoms) – Unicellular Cell Wall of Silicon not Cellulose Most Abundant Organisms on Earth Commonly Called Phytoplankton

Plant Like Protists- autotrophs Euglenophyta (Euglena) – Unicellular No Cell Wall Autotrophic & Heterotrophic Uses a flagella to move around to find food and light

Animal Like Protists- heterotrophs 1. Sarcodina - Ex) Amoeba Uses pseudopods (false foot) to move and gain energy 2. Ciliophora (Ciliates)- Ex) Paramecium and Stentor Uses small hair like projections called cilia to move and obtain energy Paramecium Amoeba Amoeba Paramecium

Animal Like Protists- heterotrophs 3. Sporozoans – Ex) Plasmodium (Causes Malaria) Do not move on their own Mostly Parasitic 4. Zooflagellates – Ex) Trypanosoma (African Sleeping Sickness) Trichonympha (Symbiotic Relationship with Termites) Giardia (Causes Amebic Dysentery) Uses Flagella to Move Plasmodium

Fungus Like Protists- heterotrophs Heterotrophic Decomposers (External Digestion) Found in Damp Moist Environments (Commonly called Molds) Reproduce by Spores (Asexual) or Alternation of Generations (Sexual) Phylums: Acrasiomycota, Myxomycota, Oomycota Caused the Great Potato Famine Oomycota
